说明： 计算矩阵连乘积 问题描述 在科学计算中经常要计算矩阵的乘积。矩阵A和B可乘的条件是矩阵A的列数等于矩阵B的行数。若A是一个p×q的矩阵，B是一个q×r的矩阵，则其乘积C=AB是一个p×r的矩阵。 (product matrix calculation problems described in scientific computation often have to calculate the matrix product. Matrices A and B can either condition is out of the matrix A few matrix B is the number of rows. If A is a p q matrix B is a q r matrix, its product C = AB is a p r matrix.)
